* <code>

*
* // Register simple parameter -h/--help
* $optionHandler->registerOption( new ezcConsoleOption( 'h', 'help' ) );

* ezcConsoleInput::TYPE_STRING,
* null,
* false,
* 'Process a file.',
* 'Processes a single file.'
* );
* $optionHandler->registerOption( $file );
*
* // Manipulate parameter -f/--file after registration
* $file->multiple = true;
*
* // Register another complex parameter that depends on -f and excludes -h
* $dir = new ezcConsoleOption(
* 'd',
* 'dir',
* ezcConsoleInput::TYPE_STRING,
* null,
* true,
* 'Process a directory.',
* 'Processes a complete directory.',
* array( new ezcConsoleOptionRule( $optionHandler->getOption( 'f' ) ) ),
* array( new ezcConsoleOptionRule( $optionHandler->getOption( 'h' ) ) )
* );
* $optionHandler->registerOption( $dir );
*
* // Register an alias for this parameter
* $optionHandler->registerAlias( 'e', 'extended-dir', $dir );
*
* // Process registered parameters and handle errors
* try
* {
* $optionHandler->process( array( 'example_input.php', '-h' ) );
* }
* catch ( ezcConsoleOptionException $e )
* {
* echo $e->getMessage();
* exit( 1 );
* }
*
* // Process a single parameter
* $file = $optionHandler->getOption( 'f' );
* if ( $file->value === false )
